Hi all. I am looking for a following system

- Microphone with a FM transmitter(Very small size..Like a sticker.)
- Receiver system with a small head phone..

If I stick that micro phone in a room… just like a sticker in the table… if somebody speaks in that room.. I should be able to hear it in the receiver…please suggest me if anybody has come across this kind of MICRO device

You’ve been watching too many James Bond movies. While transmitters are quite small these days, due to basic transmission power issues, they still are a little larger than a sticker.

For microphones, what you’re looking for is called a PZM mic. Essentially, such a mic picks up the sound vibrations from a solid surface rather than from people speaking directly at it. Transmitters, receivers? Hard to say.

There are several different companies on the Internet that specialize in such a market. Do an online search for Spy Shop and get a list of several that sell such devices. Be careful, though. A lot of their products are gimmicky and don’t perform as expected.
